SPECIFICATION forming part of Letters Patent No. 463,251,

dated November 1'7, 1891.

Application tiled February l, 1890. Serial No. 338,923. (No model.)

Be it known that I, EDWARD L. LAv'roN, a citizenof the United States,residing at Trenton, Mercer cou nty, New Jersey, have invented certainnew and useful Improvements in Coal- VVa-gons, of which the following isa specification.

My in vent-ion relates to dum ping-wagons, and more especially to thatclass of dumpingwagons which are usually employed inl the delivery ofcoal and ot'ier similar heavy and bulky objects.

Prior to my invention it has been common to' provide dumping wagons withmeans whereby the rear of the Wagon could be depressed or the frontelevated, so that the contents of the Wagon could be dumped to the rear.It has also been proposed to construct such wagons' so that-'the loadcould be dumped at the side.` y

One of the objects of my invention is to 'construct a Wagon in suchamanner that the load may be dumped either at the rear or at the sideat4 pleasure and as is most convenient in delivering the material.

A further object of -iny invention is to provide means whereby the bodyof the wagon may be elevated to any desired height and inclined at4 anydesired angle, either toward the rear or either side of therunning-gear.

A still further object of my invention is to provide meanswhereby thesevarious .objects may be attained, which shall be simple, cheap, and notliable to get out of and etl'ective, order, and capable of withstandingthe heavy Wear and tear incident to the use of such. Wagons in 'carryingand delivering heavy loads. y

To these ends my invention consists in a du mpin g-wa gon havin gthecapabilitiesherein set forth and provided with means for carrying .themout, arranged and constructed substantially as hereinafter described.

In the accompanying drawings I have illustrated the preferred embodimentof my invention, in which- Figure l is a rear View showing the Wagonbodyelevated to deliver the load at one side of the running-gear. Fig. 2 isa side view, partially in section,`showing' the wagon-body in" positionfor delivering the load to the rear of the running-gear; and Fig. 3 is aplan view to the axle at the rear, and at the front end 'connected to ahead-block 4, carrying a fifthwhecl 5, mounted on a head-block 6,supported by 'a platform 7, which in turn is supported.

by a truck-spring S, secured to the axle i). While I have found this tobe a most satisfactory running-gear for the purposes of my invention, itwill be understood that this forms no part of my invention, and anyotherwell-known and' suitable running-gear may be used.

The bed-plate l isa substantial structure of frame-work made in anydesired manner to properly support the wagon-,body 10 and the operatingmechanisms. As shown in the accompanying drawings, it consists of theside pieces l1, connected together bysnitable crosspieces 12 l2, andhaving on each side of its center a number of cross-pieces 13, althoughit is evident that this particular construction can beivaried to suitthe exigencies of the case. Mounted upon the top of this bed-piece aretwo segmental track-pieces le, and upon these track-pieces bear therollers 15, secured to the under side of the wagon-body 10, they beingpreferably mounted in stands or bearings, as shown. Normally the ends'of the' wagon-body rest upon these segmental tracks through the mediumof these rollers; but the main portion of the weight of the body and itslead is supported upon the turn-table 16, mounted in the central,portion of the bedplate. This turn-table 16 consists of asuitableframe-work, preferably circular in outline, to the under 4side of whichis secured a track i7, made of a metal plate, circular in form. Thisturn-table is connected by a pivot 18 to ene et the cross-pieces 13 ofthe bed-plate to maintain it in itscentralposition,andit is supportedupon a series of rollers 19, mountedin stands secured to thecross-piece. There may be any desired number of these rollers, and Ihave shown in the present instance six, so distributed around theperiphery of the turn-table that it willbe supported equally in alldirections. This construction l deem of considerable. importance, inthat thebearing-surface loo of the track connected to the turntable isou the under side, and this bears upon the top of the rollers 19. Inthis wayl avoid the objection tothe use of turn-tables as heretoforeconstructed, as there is no liability of the track becoming foul and`dirty through the dust and refuse or other mattei;'lod'gingy upon thetrack and interfering with its free rotation; but Iliave found lthathetrack in this forni is kept free and clear rom obstructions andallows the turn -table to rotate freely. f

The wagon-body is connected to the turntable through the medium of thelinks or pitmen 2 0, which are pivot-ally secured at one end to theunder side of the wagon-body by any suitable strips or connections andat the other end to a rod or bearing 21, mounted in the frame-work ofthe turn-table. construction it 'will be seen that the wagonbody, beingsupported .substantially uponv the turn-table and its ends resting uponthe seg.- mental tracks at the end of. the frame-Work, is, free to beturned to either side. of the wagon,v so that its rear can be brought atpleasure to the most convenient place for depositing the load.

In order to prevent the wagon-body turning too far, it being preferableto have it vat ri ght angles to the bed-plate when a side dump is to beeffected, I provide a st p 2,2, which in thel present instance I have sofwn mounted on the central cross-bar 13, which' is adapted to engagearstop 23, shown in dotted lines on the underside of the turn-table.iVhile it will be understood thatl this stop is not absolutelyessential, still I/liave found it con- 24 arranged on cach side of thewagon-body and adapted to be thrown down to engage with the sides of thebed-plate when it is desired to secure the parallelism between thewagon-bod y and the bed-plate, or to be thrown up into the positionshown in Fig. 2. This arm or lever may be a simple st0p,or, aspreferred, may he adapted t0 perform other functions.

In order to elevate the wagon-body and its load preparatory todelivering the latter, I provide on each side of the bed-plate a liftingdevice, which is preferably in the frm of a toggle-lever, consisting ofthe arms 25, pivotedtogether at one end and connected at their outerends to the screwblocks 26. These screw-blocks are mounted upon a shaft27, supported in the bcdsplato and provided From this.

'at its ends with right and left hand screws enf 4- gag-ng thescrew-blocks: .'These screwfblcks are preferably formed with a flat basebear- 'f ing upon the track-pieces 2,8,.n1ounted in the bed-plate, sothat the shaft-2,7'is relieved from the direct pressure of the weight ofthe load, and as these blocks are moved toward 'or from each other byturning the shaft they nieve along this track and are practicallysupported thereby. These togglelevers,there being one on each side, arenot connected directly with the wagon-body, but are preferably tted tobear in sockets 29, which are preferably of metal and secured to theunder side bf the wagon-sills.v Y ,t i i;

Some suitable means of turnirigfthe shafts 27 must be provided, and. Ihave shown each shaft having a squaredv end or4 key-post 30, by means ofwhich, with the aid ofa suitable wrench or key, the shafts. may beturned in.- dependently. W'hen, however, it isy desired to dump the loadat the rear, it Iis preferable to operate both of the said shafts 27sim-uhtaneously, and I` therefore provide means for doing the same, andin the present instance I have shown a cross-shaft 3l, mounted intheframe-work between the transversefsills and provided at itsV ends with abevelgear 33, se,- cured to the shafts. In order that theshafts may berotated independently, notwithstanding this beveled gear connection, Iarrange one of the bevel-gears, as 32, loosely upon the shaft 3l andprovide a suitable shifting device Si, by means of which it may bethrown.l into and out of gear with the bevel-wheel 33, so that theshafts maybe operated independently or together, as desired, by simplyship ping or uushipping the bevel-gear 32% In order that the `rear endof the wagonbody may be raised somewhat from thebedplate when the bodyand its load are raised for a rear dump, I provide the toes 35, whichare mounted in the bearings 3ti, secured upon one of the cross-piecesI3, and these toes normally rest upon the segmental track li at the rearof the wagon.

To the under side of the wagon-bod y I at'- tach lips 37 ,which areadjacent to th'e tips of the toe-pieces 35 and engage with the same asthe body is elevmed, and'thei'eby insure the. elevation of the rear ofthe body when the screwshafts and toggle-levers are being operated toprepare for a rear dump. l

' Such being the general construction of my improved dump-wagon, I willnow describe the mode of operation. iVheri it is desired to dump theload at the rear, the bevel-gear 32L being shipped into engagement'withits corresponding bevel-gear 33", power is applied to one of theshafts by a suitable wrench or key and the shaft rotated, and thisthrough the intervention of the bevehgears and their shafts causes theother shaft to rotate in unison therewith and the blocks 26 on each sideof the wagon-bod y are gradually brought toward each other, causing thetogglelcvers 25 to bear against the under portion of the body roo i i m5IIO' rzo

' elevate the rea-r and to raise the same. As the body commences torise, the links or pitmen 2O hold the wagon-bod y steady and cause it tomove forward slightly, and at the same time the toes 35, engaging thelips 37, act as levers to portion of the body from the bed-plate. lVhenthe body is raised to the desired elevation, it is held in positionwithout the intervention of any locking devices and the load isdelivered through the me dium of any suitable chute or otherwise, andthen the body is returned to its normal position by the reverse movementet' the shafts 27 and is ready for another load. `When, however, it isdesired to deliver the load at the side, the stops or arms 2t are turnedup, in the manner indicated in Fig. 2, and the body rotated upon theturn-table 16 t0 the position desired, the stops 22 limiting itsmovement in either direction. Suppose the wagon-bod y to be thrown intothe position shown in Fig. l. To elevate the trontendotthe body it isonly necessary to operate the shaft 27 on the right-hand side of thebed-plate, and to do this the bevel-gear 32a is unshipped and the key orwrench is applied to the propershaft,

` and the toggle-levers 25, which now bear upon the under side of thewagon-body,

and preferably in a socket-piece 38, operate to elevate the body to thedesired angle, and the load may be delivered. Il", however, it isdesired v to deliver the load at a higher elevation-es,

links under the rear end.

for instance, over a fence or other obstruction-the whole wagon-body maybe elevated in the manner shown in Fig. l. To do this i preferablyoperate the shaft 27 adjacent to the rear vot the wagon-body to elevateit to the desired position, when the arms or stop-pieces 2l, which areprovided with teeth on either side, as shown, may be made to engage withlugs or projections 89 on the bedplate, and thereby serve to support therear portion olV the wagon free from the toggle The shaft of thetoggle-link under the front end of the wagon is then operated and thetoggles elevated to the desired angle, and the wasgom'body is thenpractically supported by the arms 2t at the rear and the togglmarms 25at the front and is maintained or stcadied by the pitmen or links 2Oand, kept from sliding oft trom the bed-plate. 'lhe load then beinerdelivered, the parts are returned to theirnormal positions by thereverse movement of the shafts and thennlocking ot the arms 2t and therotation oi the body and the ti1rn-table lli, when the arms Q4 aredropped into their normal position and the Wagon is in condition toreceive another load. it will thus be seen that by the construction setforth l am enabled todeliverthe load at the rearor at either side of thcbed-platc, and i make irse ot the .saine elevating apparatus undereither nondition. It will l'nrther be seen that under all 'conditionsthe wagon-holly is maintained in proper relations to the tiirirtalllo bythe links O and may lwvsnplwrlod in :in elevated position at its rear,either by the toc-pieces or, the arms at the side, as the ease may be.lt will further be observed that it requires the least. expenditure ofpower to operate the wagon-body, the toggledevers and theirconnecting-screws exerting an immense pressureupon the bottom of thebody with the least expenditure of torce on the part of the operator,and as the body normally rests upon rollers it can easily be rotated toeither side.

`lv'hile I have th ns described the preferred embodiment of my inventionand the means of .operating it, it willloe understood that the detailsof construction and arrangement may be varied by those skilled in theart without materially departing from the principles of `my invention,and l therefore do not wish to be con fined to the exact constructionshown and described.
